^{Originally posted by **Fatpandac** November 21, 2022} I want to catch exceptions and then show exceptions on display or let the user send me feedback.

• At the moment, the below can be done:

  import flet as ft
  
  def main(page: ft.Page):
    page.add(
        ft.ElevatedButton(
            "Don't click me",
            on_click=lambda _: page.error("You shouldn't have clicked me!!")
        )
    )
  
  ft.app(target=main)

• Or one could create a View to which the app routes can route when an error is caught by the try-except or page.on_error event. This view could contain a form to send feedback...
